Power saving-semipersistent scheduler (PS-SPS) for voice over LTE (VoLTE) traffic was proposed in the downlink of LTE-A cell to reduce the energy consumption of the eNodeB. PS-SPS introduces the energy saving ability through a modification of traditional SPS (T-SPS) in allocating downlink Physical Resource Block (PRBs) to VoLTE users. In this paper, we first identify the drawbacks of PS-SPS that might...
Long Term Evolution-Advanced (LTE-A) that promises better support to richer applications is expected to catalyze the explosive growth in the number of subscribers and their demand for traffic. Such unprecedented growth will push the limits of energy consumption in the operators network. Hence, there is a need to introduce power saving mechanisms in LTE-A to minimize the energy consumption. In this...
Long Term Evolution-Advanced (LTE-A) is increasingly seen as a promising technology for serving Internet of Things (IoT) needs along with mobile user equipments (UEs), due to high data rate, low latency, priority services, etc. The major challenges of incorporating IoT devices into LTE-A are, a large number of IoT devices attempting to access the network in short time, their effect on existing UEs...
